Lithium Bromide Absorption Chiller

The absorption chiller operates based on a thermally driven refrigeration cycle, making it ideal for utilizing low-grade heat sources. Unlike conventional mechanical compression chillers, it does not rely on electricity to drive a compressor. Instead, it uses heat energy to power the absorption reaction between lithium bromide solution and water, thereby achieving efficient cooling. This unique mechanism allows for exceptionally high energy efficiency, especially when recovering waste heat from industrial processes.

Ideal Applications for Lithium Bromide Absorption Chillers in Waste Heat Recovery:

Available waste steam (even vented steam)

Waste heat temperature not lower than 90 °C

For lower temperature sources, thermal capacity should be at least 500,000 kcal/hr

Multiple heat sources are possible, provided they are not too far apart

Equivalent thermal sources such as exhaust gas, wastewater, condensate, or process residual heat

Cooling demand exceeds 50 RT (≈176 kW)

Plant cooling water supply must not be lower than 18 °C
